Abstract (en)
[origin: US6541113B1] Methods of making a silica-coated carbon product are described. In one method, an aqueous media or solution and a carbon product are contacted with a solution comprising a silicate substantially free of metal ions, for a sufficient time and temperature to form the silica-coated carbon product. A method of making a silica-coated product by contacting the aqueous media and a carbon product with a solution comprising monosilicic acid is also described as well as exchanging metal ions in a solution comprising metallic silicate for hydrogen ions and contacting an aqueous media and a carbon product with the solution to form silica-coated carbon products. Silica-coated carbon products resulting from these methods are also described and include a plurality of silica-coated products wherein each of the silica-coated products are substantially and uniformly coated with silica and in the substantial absence of free silica. Also, elastomeric compositions and the like containing the silica-coated carbon products are described.
